[0002] A fiber optic interface is a physical interface used to connect fiber optic cables. Usually, there are multiple channel test interfaces provided at the upper end of a fiber optic tester. By docking through the test interfaces and fiber optic plugs, the attenuation test of the fiber optic can be achieved.

[0003] For example, a fiber optic tester with the application number CN201821884985.9 includes a light source device and a test device. The light source device is a multi-channel output light source device, and multiple channels of the light source device include various interfaces; the test device is a multi-channel test device, and each channel of the test device corresponds to each channel of the light source device. A chip for calculating the attenuation of the fiber optic is provided in the test device, and a display screen for displaying the attenuation of the fiber optic is also provided on the test device, and the display screen is connected to the chip. The beneficial effect of the fiber optic tester of the utility model is that it can test the attenuation of fiber optics with different interfaces without replacing the adapter, has high test efficiency, and more accurate measurement.

[0004] In the above patent, when the fiber optic tester detects the fiber optic, it is necessary to insert the plug of the fiber optic into the channel test interface at the upper end of the fiber optic tester. During the long-term plugging and unplugging process of the channel test interface, the inserted plug is likely to become loose, thereby affecting the efficiency of fiber optic testing.

[0005] Therefore, we propose a fast test plug for fiber optic interfaces to solve the problems mentioned above. Content of the Utility Model

[0006] The purpose of the utility model is to provide a fast test plug for fiber optic interfaces to solve the problem that when the fiber optic tester detects the fiber optic, it is necessary to insert the plug of the fiber optic into the channel test interface at the upper end of the fiber optic tester. During the long-term plugging and unplugging process of the channel test interface, the inserted plug is likely to become loose, thereby affecting the efficiency of fiber optic testing as mentioned in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A fast test plug for fiber optic interfaces includes a fiber optic tester and a display screen arranged at one end of the outer wall of the fiber optic tester. A control switch is arranged on the lower side of one end of the outer wall of the fiber optic tester. Interfaces are linearly and equally spacedly arranged at the upper end of the fiber optic tester. A limiting component is fixedly installed on one side of the notch of the interface, and the limiting component is suitable for improving the stability of the fiber optic plug connected to the interface.

[0008] The limiting component includes a support mechanism and a connection mechanism movably clamped in the inner cavity of the support mechanism. A pressing mechanism is fixedly installed in the middle of the upper end of the connection mechanism. Driven by the connection mechanism, the pressing mechanism can adjust the set height and is adapted to press both sides of the upper end of the fiber optic plug.

[0009] Preferably, the support mechanism includes a concave right-angle block and an insertion groove opened in the middle of the upper end of the concave right-angle block. A plurality of circular grooves are linearly and equidistantly opened on one side of the inner wall of the insertion groove, and limiting grooves are opened on both sides of the inner wall of the concave right-angle block.

[0010] Preferably, the connection mechanism includes an insertion block and an elastic element fixedly installed at the lower end of one side of the outer wall of the insertion block. One end of the elastic element is fixedly installed with a round clamping ball.

[0012] Preferably, the pressing mechanism includes a U-shaped frame block and a fixing plate fixedly installed in the middle of the lower end of the U-shaped frame block. Placement long grooves are respectively opened on both sides of one end of the U-shaped frame block, and magnetic stickers are respectively embedded on both sides of the inner wall of the placement long grooves.

[0013] Preferably, a right-angle plate is movably installed in the inner cavity of the placement long groove, and a magnetic sticker block is fixedly installed at one end of the right-angle plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1.

The fixing plate in the middle of the lower end of the U-shaped frame block will drive the installation block and the insertion block to move downward, so that the elastic element on one side of the lower end of the insertion block contracts under the action of elastic force, driving the round clamping ball to move. When the round clamping ball moves to the notch of the circular groove, the circular groove will automatically pop out and be fixed under the action of the elastic force of the elastic element, thereby completing the fixation after the U-shaped frame block is pressed down, improving the stability during the test of the fiber optic plug and simultaneously improving the test efficiency of the fiber optic plug.

[0016] 2.

[0023] Embodiment 1: Please refer to Figures 1-4 , a fast test plug for an optical fiber interface, including an optical fiber tester 1 and a display screen 2 arranged at one end of the outer wall of the optical fiber tester 1. A control switch 3 is arranged on the lower side of one end of the outer wall of the optical fiber tester 1. A plurality of interfaces 4 are linearly and equidistantly arranged at the upper end of the optical fiber tester 1. There are a plurality of interfaces 4. A limit component 5 is fixedly installed on one side of the notch of the interface 4. The limit component 5 is adapted to improve the stability of the optical fiber plug connected to the interface 4.

[0024] The limit component 5 includes a support mechanism 51 and a connection mechanism 52 movably clamped in the inner cavity of the support mechanism 51. A pressing mechanism 53 is fixedly installed in the middle of the upper end of the connection mechanism 52. The pressing mechanism 53 can be adjusted in the set height driven by the connection mechanism 52. The pressing mechanism 53 is adapted to press both sides of the upper end of the optical fiber plug.

[0025] The support mechanism 51 includes a concave right-angle block 511 and an insertion slot 512 opened in the middle of the upper end of the concave right-angle block 511. A plurality of circular grooves 513 are linearly and equidistantly opened on one side of the inner wall of the insertion slot 512. Limit slots 514 are opened on both sides of the inner wall of the concave right-angle block 511.

[0026] The connecting mechanism 52 includes an insertion block 521 and an elastic element 522 fixedly installed at the lower end of one side of the outer wall of the insertion block 521. One end of the elastic element 522 is fixedly installed with a round clamping ball 523.

[0027] The insertion block 521 is movably installed in the inner cavity of the insertion slot 512, the limit block 525 is movably installed in the inner cavity of the limit slot 514, and the round clamping ball 523 is movably installed in the inner cavity of the round slot 513 under the elastic force of the elastic element 522.

[0028] An installation block 524 is fixedly installed at the upper end of the insertion block 521, and limit blocks 525 are fixedly installed at both ends of one side of the outer wall of the installation block 524.

[0029] The setting of the limit block 525 can improve the stability of the insertion block 521 and the installation block 524 when moving up and down.

[0030] In this embodiment: After the operator inserts the optical fiber plug into the inner cavity of the interface 4, in order to improve the connection stability of the optical fiber plug during the test, the U-shaped frame block 531 can be directly pressed down, so that the U-shaped frame block 531 drives the right-angle plate 535 to tightly press on both sides of the upper end of the optical fiber plug. At the same time, when the U-shaped frame block 531 is pressed down, the fixing plate 532 in the middle of the lower end of the U-shaped frame block 531 will drive the installation block 524 and the insertion block 521 to move downward, so that the elastic element 522 on one side of the lower end of the insertion block 521 shrinks under the elastic force, driving the round clamping ball 523 to move. When the round clamping ball 523 moves to the notch of the round slot 513, the round clamping ball 523 will automatically pop out and be fixed under the elastic force of the elastic element 522, thereby completing the fixation after the U-shaped frame block 531 is pressed down, so as to improve the stability of the optical fiber plug during the test, and such a setting can press the optical fiber plug tightly in the inner cavity of the interface 4 after the interface 4 becomes loose, so as to improve the test efficiency of the optical fiber plug.

[0031] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figure 3 , the pressing mechanism 53 includes a U-shaped frame block 531 and a fixing plate 532 fixedly installed in the middle of the lower end of the U-shaped frame block 531. Placement long grooves 533 are respectively opened on both sides of one end of the U-shaped frame block 531, and magnetic stickers 534 are respectively embedded on both sides of the inner wall of the placement long grooves 533.

[0032] A right-angle plate 535 is movably installed in the inner cavity of the placement long groove 533, and a magnetic sticker block 536 is fixedly installed at one end of the right-angle plate 535.

[0033] The right-angle plate 535 is movably installed in the inner cavity of the placement long groove 533, and the magnetic sticker block 536 can be magnetically connected according to the set length of the right-angle plate 535 and the magnetic sticker 534 or the magnetic sticker block 536 to complete the fixation of the set position of the right-angle plate 535.

[0034] In this embodiment: When the U-shaped frame block 531 is pressed downwards, the right-angle plates 535 movably installed on both sides of one end of the U-shaped frame block 531 can be withdrawn from the inner cavity of the placement long groove 533, so that the right-angle plates 535 move to one end of the notch of the placement long groove 533. After the magnetic stickers 534 and the magnetic sticker blocks 536 are magnetically fixed, the U-shaped frame block 531 can drive the right-angle plates 535 to press tightly on both sides of the upper end of the fiber optic plug, and press and fix both sides of the upper end of the fiber optic plug.

[0035] Working principle: After the operator inserts the fiber optic plug into the inner cavity of the interface 4, in order to improve the connection stability of the fiber optic plug during the test, the U-shaped frame block 531 can be directly pressed downwards. When the U-shaped frame block 531 is pressed downwards, the right-angle plates 535 movably installed on both sides of one end of the U-shaped frame block 531 can be withdrawn from the inner cavity of the placement long groove 533, so that the right-angle plates 535 move to one end of the notch of the placement long groove 533. After the magnetic stickers 534 and the magnetic sticker blocks 536 are magnetically fixed, the U-shaped frame block 531 can drive the right-angle plates 535 to press tightly on both sides of the upper end of the fiber optic plug, and press and fix both sides of the upper end of the fiber optic plug. At the same time, when the U-shaped frame block 531 is pressed downwards, the fixing plate 532 in the middle of the lower end of the U-shaped frame block 531 will drive the mounting block 524 and the insertion block 521 to move downwards, so that the elastic element 522 on one side of the lower end of the insertion block 521 contracts under the action of elastic force, driving the round clamping ball 523 to move. When the round clamping ball 523 moves to the notch of the round groove 513, the round clamping ball 523 will automatically pop out and be fixed under the action of the elastic force of the elastic element 522, thereby completing the fixation after the U-shaped frame block 531 is pressed down, so as to improve the stability of the fiber optic plug during the test. And such a setting can press the fiber optic plug tightly in the inner cavity of the interface 4 after the interface 4 becomes loose, so as to improve the test efficiency of the fiber optic plug.

[0036] The structures and working principles of the fiber optic tester, the display screen, the control switch and the interface are the same as those of the light source device, the LC interface, the ST interface, the FC interface, the power switch, the wavelength setting device, the test device, the display screen, the test button and the four-core LC optical cable in the publication number CN208971521U. This is the prior art and will not be elaborated here.
